So, what do the most important Toyota dashboard lights mean, and what do you do if one appears?

Urgent Warning Signs

On Toyota vehicles, dashboard lights come in four colors: red, yellow, green, and blue. As you might expect, a red light signifies something urgent or potentially dangerous, while the others are typically informational.

Red and Amber Toyota Warning Lights, what they mean and what to do

Red and amber lights signal issues that need prompt action. The oil pressure light means oil pressure is low, stop the vehicle and call for assistance. The brake system light can indicate low fluid or another problem, schedule an inspection as soon as possible. The battery charging light points to a charging system fault. The coolant temperature light warns of overheating. A flashing or steady check engine light means the engine control system has detected a fault, from a loose fuel cap to a more complex issue. Toyota’s official warning light glossary explains each symbol and the correct response. Our technicians follow that guidance during every inspection.

Green and Blue Toyota indicator lights, what normal looks like

Green and blue lights usually confirm that a feature is active. Examples include headlight status, cruise control, and high beams. These are informational, however if an indicator light turns yellow and a buzzer sounds, it can mean the system needs attention. When in doubt, check your model’s owner resources or visit our team for a quick scan. Toyota provides model specific indicator lists in the owner portal and digital manuals.

What to do when a Toyota dashboard light stays on

Stay calm and note the light color and symbol. If the oil pressure or temperature light is on, pull over safely and turn off the engine. For other warning lights, reduce speed, avoid hard acceleration, and plan a prompt visit for diagnostics. Toyota recommends using the warning light glossary or your digital owner’s manual for model specific advice. If the light remains on after restarting, schedule a professional scan with Springhill Toyota in Mobile. We offer a complimentary warning light scan during current service specials, and our factory trained technicians can quickly advise you on next steps.
